Which fire extinguisher class is used for fires involving combustible metals?

• A. Class B
• B. Class C
• C. Class D
• D. Class A

Answer: (C)

Fires involving combustible metals, such as magnesium, titanium, and sodium, are classified as Class D fires. This class of fire is unique because it requires special extinguishing agents that can effectively suppress fires that burn at extremely high temperatures. Regular extinguishing agents, like those used for Class A (ordinary combustibles), Class B (flammable liquids), or Class C (electrical fires), may react dangerously with combustible metals and worsen the situation. Class D fire extinguishers are specifically designed to handle these types of fires and usually contain dry powder agents such as sodium chloride or graphite that smother the flames without exacerbating the fire's intensity. Understanding this classification is crucial for ensuring safety and effective firefighting in environments where combustible metals are present.
